  • Method and apparatus for heating a flow of gaseous fluid by successive thermal exchanges
    Patent number: 5061177
    Abstract: The invention relates to a process and a device for indirectly heating a flow of gaseous fluid. According to the invention, the flow of fluid to be heated is first subjected to a first heat exchange with combustion products, in a heat exchanger (3), and is subsequently subjected to a second heat exchange with a heat-exchanging fluid circulating in a second heat-exchanger (5). The flow of fluid to be heated is then circulated in a third exchanger (7) where it is subjected to a heat exchange with the combustion products before the latter are used at the time of the first heat exchange. The third heat exchanger (7) can comprise radiating tubes (51) and convection surfaces for heating the flow of fluid in circulation, essentially by convection.
